What is a median premium?

On every route, the cheapest carrier sets the floor and every other carrier's fare is measured as dollars above it, in the same travel week. A carrier's median premium is the middle of those gaps across its observed returned route sample. Zero means it was lowest or tied on at least half that sample. Each gap compares recorded fares within an airport pair, cabin and travel week; routing can differ. Airlines have different route samples, so their network medians do not isolate airline pricing from route mix.

Why is a carrier's median blank?

Because it returned accepted fares on fewer than 3 of the routes in the grid in that cabin. One or two observations are an anecdote, and a median of them would ship a number that looks like a pattern. The carrier is still in the file with its route count and its cheapest fare, and the ranked column says explicitly that no median is published.

Why does the file not include every fare?

The per-route fares power the airline rankings and every head-to-head comparison on the site, and they are held back for the same reason the archive of past city grids is. What is published is one row per airline carrying the figures those pages show. That is enough to check any ranking on the site, and it is the form a reader actually uses.

Why is the product score out of three dimensions for some carriers?

Of the seven dimensions the site scores a cabin on, only four can be known without being on the aircraft: Seat, IFE, Lounge, and Value, the last computed from this grid. Value is withheld when the carrier has too few priced business routes, so those carriers are scored on three. Service, food and ground handling are scored only in reviews where the author has flown the cabin, and never appear in this file.

Why is there a flown_by_author column in a data file?

Because it separates what was measured from what was experienced, which is the distinction the whole site is built on. The fare and product columns come from published data. The flown column records whether Jon has personally flown the carrier on a Europe route, so a reader can see which airline pages carry firsthand judgment on top of the numbers and which are researched only.

Dataset

The transatlantic carrier grid, by airline

46 airlines observed in US to Europe searches, each with its returned route sample, its median premium over the cheapest carrier on the same route, how often it was cheapest, and its verified cabin score, in economy and business, for travel November 8–14, 2026. One row per airline.

Download CSV Download JSON46 rows · observed October 17, 2026 · CC BY 4.0

Partial carrier sample: complete evidence for 2,615 of 2,652 planned route/cabin cells; 37 unresolved and 0 not collected. These gaps are excluded from fare rankings and comparisons, not treated as airline absence. Coverage and methods.

46: Airlines, 36 ranked in economy and 36 in business
5,168: Economy fares behind the aggregates, on 977 routes
4,886: Business fares, on 962 routes, a separate pass for the same week
1,326: Routes planned; the unpriced ones are declared, not dropped

What one row is

One row is one airline. Behind it sit every fare that airline returned in the grid: the same fixed travel week, November 8–14, 2026, on its accepted observed routes between the 26 US gateway metros and 51 European airports. On each route, the cheapest carrier sets the floor, and every other carrier’s fare is recorded as dollars above it. The row carries the median of those gaps, the number of routes it was cheapest on, its route count, and its cheapest fare anywhere, once for economy and once for business.

The fares were collected between October 12, 2026 and October 17, 2026, origin by origin, with every carrier on a route captured in one session. Each within-route comparison uses quotes from the same observation day; differences observed on other days are separate historical context. A carrier with fewer than 3 routes in a cabin has no median published in that cabin, and the file says so in its own column.

The product score comes from a separate dataset of verified cabins, recorded per aircraft because the airframe often decides whether a business seat has direct aisle access. The file carries each carrier’s best-scoring aircraft and how many dimensions that score rests on. How the four data-scorable dimensions are built, and why three are never scored from data, is on How we review.

Column	Meaning
carrier	Carrier slug, matching /airlines/<carrier> on the site where the carrier has a page.
airline	Airline name.
iata	IATA airline code.
alliance	Alliance membership as verified 2026-09-01: Star Alliance, SkyTeam, oneworld or None. A group subsidiary is not a member.
kind	european-flag, low-cost, us-major or other.
hub	Connecting airport the carrier routes transatlantic traffic through, where that is its play. Blank otherwise.
economy_routes	Routes on which the carrier returned an economy fare in the fixed-week grid, out of 1,326 planned (26 US gateways by 51 European airports).
economy_ranked	true when economy_routes is at least 3, the threshold below which no median is published.
economy_median_premium_usd	Median dollars above the cheapest carrier on the same route in the same travel week, across the carrier's economy routes. Blank when unranked.
economy_cheapest_on_routes	Economy routes on which the carrier was the cheapest option, a premium of $0.
economy_lowest_fare_usd	Cheapest economy fare the carrier returned anywhere in the grid. A fact about one route, not about the carrier's typical price.

Limitations, stated

One week. Every figure describes November 8–14, 2026. A carrier that discounts a different week, or a different season, is not captured. The week was fixed before collection and is not chosen to favor anyone.
Coverage sets the median. A carrier’s median is only as trustworthy as the routes behind it. A carrier observed from five gateways has a median about that returned sample. The route count sits beside every median for that reason.
Lowest fare is a fact about one route. The cheapest fare a carrier returned anywhere is not its typical price, and should not be quoted as one.
Unpriced is declared. Of 1,326 planned routes, 324 returned no economy itinerary and 352 no business itinerary from any carrier. Those are recorded as unpriced, not as expensive, and they are not in this file’s counts.
Product is not experience. The score covers what can be read from a published specification and a fare grid. Service, food, and how an airline recovers a missed connection are not in it.
